Strange SMD resistors code

    Looking at a mobo, trying to reverse some bit of it, I just notices that
    the resistors values aren't noted following the ordinary 3 or 4 figures
    code, but rather 2 figures and one letter, like 93A, 30C, 01C, 07B...

    A quick search didn't show anything.

    Anyone have pointers to this?

    There's a standard set of 2-digit+1-letter codes that refer to values.
    Search for EIA-96. If that's right, your resistors are 90.9, 20.0k,
    10.0k, 1.15k.

    The codes on some resistors are rather like the codes on some ICs - they
    do not convey meaningful information about the value of the part.
    Those codes ring a bell and may be Vishay parts, so you might find the
    answer there.

    Cheers

    Thanks.
    Short after posting my question I've found some reference.
    It seems to be used manly on 1% 0603 where there's no room for four
    digits. Strange that I didn't notice it before.

    *** Exactly. I've seen them many times before.
